Question 902748: Find the coordinates of the missing endpoint if P is the midpoint of NQ
1. N(2,0) P(5,2) 2. N(5,4) P(6,3) 3. Q(3,9) P(-1,5)

More importantly, I want to know how to solve this type of problems. What's the formula?... If there is.

Midpoint Pt(x,y): ( %28x%5B1%5D+%2B+x%5B2%5D%29%2F2, %28y%5B1%5D+%2B+y%5B2%5D%29%2F2++%29)
N(2,0)
Q(8, 4) Midpoint P(5,2)
